大直徑鋼波紋管拼裝方法你知道嗎？

1、搭(da)(da)設拼裝支(zhi)架:搭(da)(da)設腳(jiao)(jiao)手架根據(ju)(ju)波紋(wen)管(guan)(guan)的直徑提(ti)前確(que)(que)定，采用管(guan)(guan)扣(kou)連接鋼(gang)管(guan)(guan)的方式(shi)搭(da)(da)設腳(jiao)(jiao)手架，形式(shi)分A型和B型腳(jiao)(jiao)手架長(chang)度一般(ban)長(chang)25m、克0、6m、高為(wei)2d3(d為(wei)波紋(wen)管(guan)(guan)直徑)，B型腳(jiao)(jiao)手架一般(ban)克為(wei)25m高依據(ju)(ju)波紋(wen)管(guan)(guan)直徑大小拼裝接縫(feng)位置確(que)(que)定尺(chi)寸。腳(jiao)(jiao)手架按上述(shu)尺(chi)寸搭(da)(da)設便于(yu)施工、

2、拼裝(zhuang)類型與搭接(jie)方式：拼裝(zhuang)以中心(xin)軸線為基準，由(you)中心(xin)向兩端(duan)對(dui)稱進行安裝(zhuang)，直至兩端(duan)。1斷(duan)面(mian)(奇(qi)數(shu)斷(duan)面(mian))、Ⅱ斷(duan)面(mian)(偶數(shu)斷(duan)面(mian))、加強斷(duan)面(mian)(偶數(shu)斷(duan)管(guan)管(guan)片(pian)）

3、波紋管(guan)(guan)拼裝(zhuang)：采(cai)用刻槽法施工的地基，安(an)(an)裝(zhuang)吊車依據刻槽深度(du)，依次安(an)(an)裝(zhuang)底(di)部(bu)管(guan)(guan)片(pian)(pian)。底(di)部(bu)管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)完成(cheng)后對剩余管(guan)(guan)片(pian)(pian)進行安(an)(an)裝(zhuang)。管(guan)(guan)片(pian)(pian)安(an)(an)裝(zhuang)同平基上(shang)的鋼波紋管(guan)(guan)施工。

首圈(quan)(quan)(quan)(quan)波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)圈(quan)(quan)(quan)(quan)為奇數(shu)斷(duan)面(mian)，拼裝(zhuang)(zhuang)時應將(jiang)(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立(li)于地上(shang)(shang)安裝(zhuang)(zhuang)，使(shi)用(yong)(yong)鐵鉤的(de)(de)(de)一(yi)端(duan)勾住I斷(duan)面(mian)片(pian)(pian)(pian)(pian)(pian)(1#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)螺(luo)絲囗，用(yong)(yong)12噸的(de)(de)(de)吊車勾住鐵鉤的(de)(de)(de)另一(yi)端(duan)，將(jiang)(jiang)(jiang)波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)立(li)于墊(dian)層上(shang)(shang)，然后(hou)使(shi)用(yong)(yong)同樣的(de)(de)(de)辦法將(jiang)(jiang)(jiang)第二片(pian)(pian)(pian)(pian)(pian)(6#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian))波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)按圖(tu)3、21斷(duan)面(mian)所示(shi)的(de)(de)(de)搭接(jie)方式放置，使(shi)用(yong)(yong)撬棍將(jiang)(jiang)(jiang)管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)螺(luo)栓口對齊，將(jiang)(jiang)(jiang)提前準備好(hao)的(de)(de)(de)螺(luo)栓螺(luo)紋(wen)(wen)部涂上(shang)(shang)渢滑劑，由內冋外插入孔位(wei)；波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)外側套(tao)(tao)上(shang)(shang)凹墊(dian)圈(quan)(quan)(quan)(quan)或凸墊(dian)圈(quan)(quan)(quan)(quan)，遇波(bo)(bo)(bo)(bo)(bo)(bo)使(shi)用(yong)(yong)凸墊(dian)圈(quan)(quan)(quan)(quan)，遇波(bo)(bo)(bo)(bo)(bo)(bo)峰使(shi)用(yong)(yong)凹墊(dian)圈(quan)(quan)(quan)(quan)墊(dian)圈(quan)(quan)(quan)(quan)外側旋上(shang)(shang)螺(luo)母，在用(yong)(yong)套(tao)(tao)筒扳(ban)手預緊螺(luo)母，然后(hou)使(shi)用(yong)(yong)電動扳(ban)手緊固螺(luo)母兩塊(kuai)板片(pian)(pian)(pian)(pian)(pian)洤全部安裝(zhuang)(zhuang)完畢;波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)的(de)(de)(de)螺(luo)栓安裝(zhuang)(zhuang)完畢后(hou)，需采用(yong)(yong)專(zhuan)用(yong)(yong)注膠槍于端(duan)部接(jie)合處、緊回件連接(jie)的(de)(de)(de)螺(luo)栓孔空(kong)隙處涂抹中性硅酮(tong)耐候膠。緊接(jie)著按2#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、5#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、3#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)、4#管(guan)(guan)片(pian)(pian)(pian)(pian)(pian)的(de)(de)(de)施工拼裝(zhuang)(zhuang)順(shun)序(xu)，拼裝(zhuang)(zhuang)好(hao)首圈(quan)(quan)(quan)(quan)波(bo)(bo)(bo)(bo)(bo)(bo)紋(wen)(wen)管(guan)(guan)圖(tu)36偶數(shu)、奇數(shu)斷(duan)面(mian)交替拼裝(zhuang)(zhuang)順(shun)序(xu)

4、加強斷面拼裝

當波紋管涵直徑較大、填土高度較高時(shi)，必須設置加(jia)(jia)強(qiang)管片，稱為加(jia)(jia)強(qiang)圈(quan)”，加(jia)(jia)強(qiang)斷面的(de)管片安裝工序。
